Download or read book Applications of Neutron Powder Diffraction written by Erich H. Kisi and published by OUP Oxford. This book was released on 2008-10-02 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book covering the theory, practicalities, and the extensive applications of neutron powder diffraction in materials science, physics, chemistry, mineralogy and engineering. Various highlight applications of neutron powder diffraction are outlined in the introduction, then the theory is developed and instrumentation described sufficient for a return to the applications. The book covers the use of neutron powder diffraction in the solution (hard) and refinement (more straightforward) of crystal and magnetic structures, applications of powder diffraction in quantitative phase analysis, extraction of microstructural information from powder diffraction patterns, and the applications of neutron diffraction in studies of elastic properties and for the measurement of residual stress. Additional theory to underpin these various applications is developed as required. Much of the material should be accessible to senior undergraduates in science and engineering, as well as to graduate students and more senior researchers with an interest in the technique.

This book was released on 2006 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Na-deficient NaxCoO2 is intercalated with water1 or heavy water2, it becomes a superconductor. The maximum critical temperature of 4.5 K is found for the composition NaxCoO2yD2O (x= 0.3 and y=1.4). In spite of its low transition temperature, several similarities with high temperature superconducting cuprates have raised interest in this compound. Nevertheless, up to now, a clear understanding of the role of water has not been achieved. Since superconductivity appears only when water is inserted in the parent compound, the goal of this research work was to understand what kind of effect water intercalation has in terms of electron conduction and superconductivity. Neutron scattering played a crucial role in this study because of its ability to determine the accurate positions of light elements such as hydrogen or deuterium. We have focused our attention on the intra-molecular range of D2O, studying the structural changes that take place within the (heavy) water molecules themselves. In order to do this the distance correlations D-D, D-O, and O-O have been studied. Powder neutron diffraction data of the deuterated sodium cobaltate have been analyzed using the Pair Density Function (PDF) technique, which gives information about the local structure of the water molecules. The peaks of the PDF of the neutron diffraction data, in fact, give directly in real space the distances between pair of atoms, in this case the distances D-D, D-O, and O-O. If a peak shifts to a lower (or higher) value of r (Å) it means that the bond between that particular pair of atoms has become shorter (or longer). In this way it was possible to determine any change in the geometry of the water molecules. The results obtained show that the D-D distance and the D-O-D angle in Na0.35C0O21.4D2O are significantly different from those of ordinary water (D2O). Two coexisting distributions of possible D-O-D bond angles are observed. We speculate that the altered geometry of the intercalated water molecules is due to a modification of the dynamics of the hydrogen bond. In this case, water may be embedded in an electronically active environment and indirectly participate in electronic conduction.

Download or read book Neutron Scattering in Condensed Matter Physics written by Albert Furrer and published by World Scientific Publishing Company. This book was released on 2009-05-22 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutron scattering has become a key technique for investigating the properties of materials on an atomic scale. The uniqueness of this method is based on the fact that the wavelength and energy of thermal neutrons ideally match interatomic distances and excitation energies in condensed matter, and thus neutron scattering is able to directly examine the static and dynamic properties of the material. In addition, neutrons carry a magnetic moment, which makes them a unique probe for detecting magnetic phenomena. In this important book, an introduction to the basic principles and instrumental aspects of neutron scattering is provided, and the most important phenomena and materials properties in condensed matter physics are described and exemplified by typical neutron scattering experiments, with emphasis on explaining how the relevant information can be extracted from the measurements.

This book was released on 2008-11-24 with total page 921 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2007 ARW “Using Carbon Nanomaterials in Clean-Energy Hydrogen Systems” (UCNCEHS’2007) was held in September 22–28, 2007 in the remarkable town Sudak (Crimea, Ukraine) known for its heroic and unusual fate. In the tradition of the earlier conferences, UCNCEHS’2007 meeting served as an multidisciplinary forum for the presentation and discussion of the most recent research on transition to hydrogen-based energy systems, technologies for hydrogen production, storage, utilization, carbon nanomaterials processing and chemical behavior, energy and environmental problems. The aim of UCNCEHS’2007 was to provide the wide overview of the latest scientific results on basic research and technological applications of hydrogen interactions with carbon materials. The active representatives from research/academic organizations and governmental agencies could meet, discuss and present the most recent advances in hydrogen concepts, processes and systems, to evaluate current progress and to exchange academic information, to identify research needs and future development in this important area. This ARW should help further the progress of hydrogen-based science and promote the role of hydrogen and carbon nanomaterials in the energy field.

Download or read book Physics of Nuclei and Particles written by Pierre Marmier and published by Academic Press. This book was released on 2013-10-22 with total page 685 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physics of Nuclei and Particles, Volume II explores the prevalent descriptive methods used in nuclear and particle physics, with emphasis on the phenomenological and model-based aspects. The interactions of nuclear particles are discussed, along with nuclear forces and potentials and scattering and reaction models employed in nuclear physics. The nuclear structure and models of the nucleus are also considered. Comprised of four chapters, this volume begins with a review of the characteristics of nucleons and other particles that play a role in nuclear interaction processes in order to gain further insight into the underlying physical problems. Neutron physics, antinucleons, deuteron physics, and two-body nuclear forces are highlighted, together with three- and four- nucleon systems and heavy-ion physics. The next three chapters deal with nuclear forces and potentials, as deduced from nuclear dynamics (scattering and polarization); scattering and reaction models used in nuclear physics; and nuclear models such as the shell model, models of deformed nuclei, and many-body self-consistent models. The book concludes with an analysis of the Brueckner-Bethe-Goldstone theory of nuclear matter. This book will be of interest to physicists.
